Yesterday, Apple officially announced iOS 10 at its Worldwide Developers Conference in San Francisco. The upcoming mobile operating system 10 primary new features, going as follows:

User Experiencer: This incorporates an all-new lock screen, a refreshed overall look, the Control Center looks new, the lock screen now has widgets, and 3D Touch features are added to the lock screen. Widgets also appear in the Today view as usual plus the 3D Touch quick actions menu for new iPhones.

Siri: Starting with iOS 10, developers will have the ability to add features to Siri using a new SDK. Federighi used WeChat as an example. The UI for Siri looks similar, but now apps that work with Siri have much richer interface.

Sierra, which might otherwise be known as “10.12”, includes a swath of new changes, including a much-updated Siri, which will be incorporated into the operating system and feature a Siri icon within the Dock that activates when clicked upon. During the macOS Siri demo at WWDC, Apple VP Craig Federighi used Siri to find files and followed up the search to refine the results. Federighi also showed how Siri results can be integrated into other Apple apps, such as Reminders.

Among the mucho announcements during the WWDC keynote, Craig Federighi, Apple’s senior vice president of software engineering, announced that the company will begin incorporating “Pay with Apple Pay” buttons. The new feature will be available when the latest version of macOS, Sierra, becomes available to Mac users this fall.

Federighi said the online “Apple Pay” button will require users to authenticate their identity from a TouchID device—iPhone or Apple Watch—to preserve the security of their transactions.

Rumors have come down the pipe from assorted suppliers that Apple may announce updated MacBook Air notebooks this month as opposed the August. The rumor also states that Apple might refresh its entire MacBook line earlier than expected,

The report, citing “a reliable Chinese supplier,” mentions earlier rumors that Apple will discontinue the smaller 11-inch MacBook Air to focus on 13-inch and all-new 15-inch models. All of the new MacBook Air and MacBook Pro models are expected to be equipped with Thunderbolt 3/USB-C ports, while USB-A, MagSafe 2, and Thunderbolt 2 ports found on existing models will allegedly be removed.

With rumors that Apple is working on a device to compete with Amazon’s Echo, it’s been suggested that a fifth-generation version of the Apple TV will eventually get its own microphone and speaker, and that Apple will be improving its computing infrastructure to handle more Siri queries.

Supporting these developments will be the previously-rumored Siri SDK for developers, allowing them to hook third-party apps into the platform, the source noted.

Following up on the slew of announcements from this year’s Worldwide Developers Conference, Apple late Monday posted to its website a full version of this year’s WWDC keynote address. The keynote clocks in at just under two and a half hours from Bill Hader’s comedic intro to a musical performance by The Weeknd.

During the WWDC keynote, Apple announced that its upcoming Wallet app will replace Passbook, but function in the same way: You’ll still store your concert tickets in Wallet alongside your Apple Pay card information. The program will also store reward cards for stores like Kohl’s and JCPenney as Apple Pay will start supporting retail loyalty programs this fall.
